Laravel Sail 重建默认数据库

Question

根据文档：

此外，当 MySQL 容器启动时，它将确保存在名称与 DB_DATABASE 环境变量的值匹配的数据库。

我的.env文件看起来像这样。

DB_CONNECTION=mysql
DB_HOST=mysql
DB_PORT=3306
DB_DATABASE=test
DB_USERNAME=root
DB_PASSWORD=

然而，当我尝试通过 运行迁移时sail artisan migrate，我得到了这个错误： SQLSTATE[HY000] [1049] Unknown database 'test' (SQL: select * from information_schema.tables where table_schema = test and table_name = migrations and table_type = 'BASE TABLE')

我试过的：

• 一起删除 docker 容器和图像。
• 运行sail build --no-cache（尝试完全重建一切）
• 运行时sail shell，我进入 MySQL 并显示所有数据库。我可以在那里看到默认的 Laravel 数据库。

你怎么告诉sail创建正确的DB_DATABASE？

我的docker-compose.yml：

Answer 1

案例 - 重用已创建的 Docker 卷

如果使用 停止 Sail sail down，数据卷将保留在 Docker 主机上而不会被删除。

当 Sail 停止时，用于sail down -v删除现有的 Docker 卷数据。

首先sail up，DB_DATABASE=forge

首次启动 Sail 时，会在 Docker 主机上创建一个卷。

grep DB_DATABASE .env
DB_DATABASE=forge

docker volume ls
DRIVER    VOLUME NAME

sail up -d
Creating network "test_sail" with driver "bridge"
Creating volume "test_sailmysql" with local driver
Creating volume "test_sailredis" with local driver
Creating test_mailhog_1 ... done
Creating test_mysql_1   ... done
Creating test_redis_1   ... done
Creating test_laravel.test_1 ... done

docker volume ls
DRIVER    VOLUME NAME
local     test_sailmysql
local     test_sailredis

sail mysql
mysql> show databases;
| forge              |

但是，当我退出 Sail 时，Docker 容器被删除，但卷没有被删除。

sail down
Stopping test_laravel.test_1 ... done
Stopping test_mailhog_1      ... done
Stopping test_redis_1        ... done
Stopping test_mysql_1        ... done
Removing test_laravel.test_1 ... done
Removing test_mailhog_1      ... done
Removing test_redis_1        ... done
Removing test_mysql_1        ... done
Removing network test_sail

docker volume ls
DRIVER    VOLUME NAME
local     test_sailmysql
local     test_sailredis

二sail up、DB_DATABASE=test

如果您在相同的目录名称中启动第二个 Sail，则将重用已创建的 Docker 卷。

grep DB_DATABASE .env
DB_DATABASE=test

sail up -d
Creating network "test_sail" with driver "bridge"
Creating test_mysql_1   ... done
Creating test_redis_1   ... done
Creating test_mailhog_1 ... done
Creating test_laravel.test_1 ... done

docker volume ls
DRIVER    VOLUME NAME
local     test_sailmysql
local     test_sailredis

由于数据存在于test_sailmysql第一次运行时创建的卷中，因此不会执行新的数据库创建任务。

sail mysql
  ERROR 1049 (42000): Unknown database 'test'

sail artisan migrate
  Illuminate\Database\QueryException
  SQLSTATE[HY000] [1049] Unknown database 'test' (SQL: select * from information_schema.tables where table_schema = test and table_name = migrations and table_type = 'BASE TABLE')

删除现有卷后启动

sail down -v
...
Removing volume test_sailmysql
Removing volume test_sailredis

sail up -d
...
Creating volume "test_sailmysql" with local driver
Creating volume "test_sailredis" with local driver

sail mysql
mysql> show databases;
| test               |

sail artisan migrate

sail down 选项

sail down -h

    -v, --volumes           Remove named volumes declared in the `volumes`
                            section of the Compose file and anonymous volumes
                            attached to containers.
